Disk capacity
Each logged CAN message occupies 24 bytes on the disk. The disk is divided into
two equal-sized parts: one for the error frames with pre- and post-trigger buffers
and one that logs all CAN messages.
The disk size is 1 GB, so the “log all” portion of the disk accommodates
approximately 20,000,000 messages. At 500 messages per second, this means
that slightly more than 11 hours are recorded before the FIFO buffer wraps and
begins overwriting the beginning data.

CAN connector
The Kvaser Memorator Light has one CAN channel. The CAN channel connector
is the 9-pin male D-SUB connector shown in Figure 4 with the pin-out described
